I apologize for any toes I might have stepped on and if I came off as sounding a bit full of myself. What I meant by a dead stop in my progress is that my musical interpretation and my teacher's are different, and I am not wanting to yield too much more. I understand that Russian music and German music are very lyrical. I should have used a better description. I guess my musical interpretation comes from the kind of music I played during high school. My director had us play Shostakovich's 5th symphony finale, Ballet Sacra by Hollsinger (sp), and many pieces resembling that. Again, not trying to offend anyone with this, but from what I have heard of French music, it tends to be somewhat boring, in my opinion. There are exceptions to every rule though, my favorite solo is the Carnival of Venice. Also, I was not trying to find grounds to dismiss my teacher. I was wanting to get opinions of advanced players since I am honestly pretty terrible. Pretty much the only thing I can do well is play high. Reading the responses, I believe I was probably just being immature about this situation and should just suck it up and just do what he says to do. Lastly, I feel I offended some people, and I greatly apologize. I will work at taking more possible opinions into account. Though I never got an answer to this question: what is making it so hard to switch from cornet to trumpet? My cornet is a Bach Strad and my trumpet is a Bach Omega. I practice as much as I can on my trumpet, but it still feels like more work than play. I feel like I can have fun on my cornet, but not on my trumpet.
